Good morning,
I started fiddling around with real basic stuff using a UV5R HAM radio, connecting to a repeater, setting tones, etc... but discovered GMRS and was attracted to it due to the more relaxed nature of users and the ability to purchase a family license. I've been playing around with some handhelds with my kiddo which led me down the road to a portable GMRS repeater (thank you Notarubicon). I purchased the Retevis RT97L portable repeater kit which includes their fiberglass antenna and coaxial cable. I'm looking for some tips trouble shooting my current set up, but I know how forums can go so I want to preface a few things:
I've read the initial post pinned and am not seeking advice on how I "should have" done things. I am only looking for advice on current setup and trouble shooting for performance.
There are no published GMRS repeaters within my location - I purchased the items I did to fart around with this as a hobby and have some fun with my kid. It is not about trying to reach 15 miles or anything like that.
Current set up:
Multiple Baofeng GM-15PRO handhelds with ABBREE AR 771 antennas
Retevis RT97L mobile repeater inside garage.
Retevis GMRS fiberglass antenna mounted on a mast on gable of garage - approximately 25' off ground
No major obstructions around the antenna. I'm in a rural town of less than 10,000 - mostly two story buildings - nothing really taller than that.
I would be totally thrilled if I could transmit 1 - 1 1/2 miles from my garage. Not looking for anything more than that, but current state is that I cannot. I can connect to the repeater (467.72500/462.72500) and talk between two handhelds but am limited to about a half mile.
I will say that when I screwed the coax into the bottom of the antenna it didn't seem to screw on very well so I used a small pair of Channellocks and may have overtightened. It seemed like something started to spin that shouldn't have Is there a way to test to see if my antenna is even working properly before we go down the road of hypothesizing what the setup is even capable of? We just got the damn thing mounted to the roof this weekend and I hate the thought of having to pull the whole thing down again. There is no good way to do it....
I appreciate any help you can offer.
